What is the science behind the recommendation to seal off rooms?
• Duct tape was tested as part of a study on chemical protective clothing materials. • In this study, it was concluded that duct tape provided at least a temporary seal against permeation by stimulants of common chemical agents, including GB, VX, mustard and pesticides. • Depending on the chemical agent, duct tape resisted permeation by a liquid agent for 3 hours to more than 24 hours. • The study tested duct tape of 10 mil (0.01 in.) thickness. • Plastic sheeting was tested as part of a test using live chemical warfare agents conducted at the Chemical Defense Establishment in Porton Down, England in 1970. • Agents tested included H and VX. Varying thickness were tested, including 2.5 mil (0.0025 in.), 4 mil (0.004 in.), 10 mil (0.01 in.) and 20 mil (0.02 in.).
